The European nations are acknowledged to have come, in successive waves of migration, from Asia. Modern ethnologists generally agree that the Indian races of America are derived from Mongoloid sources in Eastern Asia, either through Polynesia or by way of the Aleutian Islands. Bunsen, Philos. of Universal History, 2:112—the Asiatic origin of all the North American Indians “is as fully proved as the unity of family among themselves.” Mason, Origins of Invention, 361—“Before the time of Columbus, the Polynesians made canoe voyages from Tahiti to Hawaii, a distance of 2300 miles.” Keane, Man Past and Present, 1-15, 349-440, treats of the American Aborigines under two primitive types: Longheads from Europe and Roundheads from Asia. The human race, he claims, originated in Indomalaysia and spread thence by migration over the globe. The world was peopled from one center by Pleistocene man. The primary groups were evolved each in its special habitat, but all sprang from a Pleiocene precursor 100,000 years ago. W. T. Lopp, missionary to the Eskimos, at Port Clarence, Alaska, on the American side of Bering Strait, writes under date of August 31, 1892: “No thaws during the winter, and ice blocked in the Strait. This has always been doubted by whalers. Eskimos have told them that they sometimes crossed the Strait on ice, but they have never believed them. Last February and March our Eskimos had a tobacco famine. Two parties (five men) went with dogsleds to East Cape, on the Siberian coast, and traded some beaver, otter and marten skins for Russian tobacco, and returned safely. It is only during an occasional winter that they can do this. But every summer they make several trips in their big wolf-skin boats—forty feet long. These observations may throw some light upon the origin of the prehistoric races of America.”
